Abstract: A lens of a vehicular headlight is mounted on a vehicle and includes an incident surface through which light from a light source enters and an emission surface from which light entered from the incident surface is emitted. At an upper edge area including an upper end in an on-board state, the emission surface has a shape allowing a portion of light entered through the incident surface and reached the upper edge area to be internally reflected rearward in the on-board state after being internally reflected toward the incident surface side from the emission surface and internally reflected toward the emission surface side from the incident surface.

Abstract: When light is off, a transparent appearance is obtained, while when the light is on, light is seen through a transparent spot. The present invention includes a light source portion and a reflective portion. The light source portion emits light. The light source portion is disposed at a position shifted with respect to an emitting direction of emitted light from the reflective portion. The reflective portion reflects the light from the light source portion and emits it in a predetermined direction. The reflective portion is constituted by a transparent member with a refractive index at least in a visible light area larger than 1. As a result, in the present invention, the transparent appearance is obtained when the light is off, while the light is seen through the transparent spot when the light is on.

Abstract: A vehicle lamp, which can make objects in a lamp chamber invisible, includes: a lamp housing and a lamp lens forming a lamp chamber, an excitation-light irradiation unit, a light conversion unit, and an optical filter disposed in the lamp chamber. The optical filter is disposed between the excitation-light irradiation unit and the light conversion unit and blocks light in a specific wavelength range. As a result, such a phenomenon that an image from an outside is seen in the lamp chamber through the lamp lens or an object in the lamp chamber is seen through the lamp lens can be suppressed, and the object in the lamp chamber can be made invisible.

Abstract: A lighting fixture for a vehicle efficiently releases heat from a light source while inhibiting moisture from entering the light source side. The lighting fixture includes: a light source; a heat dissipating member which dissipates heat from the light source, the light source being placed on an installation surface of the heat dissipating member; and a socket to which the heat dissipating member is attached. The heat dissipating member has a heat dissipating fin part protruding from a heat dissipating surface on the side opposite to the installation surface, and a heat dissipating-side positioning part (positioning projection) provided on the heat dissipating surface. The socket has, on an attachment surface, a fin recess into which the heat dissipating fin part fits, and a socket-side positioning part (positioning hole) which determines the positional relationship between the heat dissipating member and the socket in cooperation with the heat dissipating-side positioning part.

Abstract: To provide a vehicular lamp system capable of reducing a replacement frequency of a vehicular lamp. A vehicular lamp system includes a vehicular lamp having a plurality of elements capable of emitting light to a corresponding irradiation region and a detection unit that detects presence or absence of an abnormality in the plurality of elements, and a notification unit that notifies abnormality information concerning occurrence of the abnormality when the abnormality was detected in the element, in which the notification unit notifies the abnormality information with contents, which are different between a case where the abnormality is detected in the target element capable of emitting light to a predetermined region among the plurality of elements and a case where the abnormality is detected in the non-target element different from the target element among the plurality of elements.

Abstract: A vehicular lamp includes: a main light source that emits light for forming a predetermined irradiation pattern; an optical member that allows the light emitted from the main light source to travel toward a front side in an irradiation direction to form the irradiation pattern; a heat dissipation member that releases heat from the main light source to outside; and a light guide member that guides light from an auxiliary light source provided as a separate body from the main light source. In the heat dissipation member, the heat dissipation member is provided with an opening part that opens a mounting surface provided with the main light source, and the light guide member guides light from the auxiliary light source toward the mounting surface through the opening part.
